| 摘 要： | 根据计算机软硬件条件引进开发数值模式在ＰＶＭ环境下的并行版本，于１９９６年６月开始模式并行计算业务实验。结果表明：在数值预报中采用并行计算技术后，其ＣＰＵ加速比达到３．２１，并行效率达８０％，模式并行计算版本运行基本稳定，计算结果与串行计算结果基本一致。

| Abstract: | Working together with Meteorology Burro of China, LRCM tests to develop parallel arithmetic under PVM environment by local computer conditions as well as to develop the high resolving power regional nested weather model. From June 1996, parallel arithmetic weather model is used and the result shows that the CPU accelerating ratio is 3.21, the parallel efficiency is 80%, the circulate is stable and the outcome is consistent with serial arithmetic essentially. |
